Quotation by Rémy De Gourmont

Cliche refers to words, commonplace to ideas. Cliche describes the form or the letter, commonplace the substance or spirit. To confuse them is to confuse the thought with the expression of the thought. The cliche is immediately perceivable; the commonplace very often escapes notice if decked out in original dress. There are few examples, in any literature, of new ideas expressed in original form. The most critical mind must often be content with one or the other of these pleasures, only too happy when it is not deprived of both at once, which is not too rarely the case.
